It looks like all the partying Scott Disick did in Cannes is finally catching up to him.

The 34-year-old had a wild couple of days while vacationing in France during the Cannes Film Festival last week, but all good things must come to an end and Scott had to pack up his things and get back to reality. The father-of-three was spotted arriving at LAX on Friday, June 2 — and he didn't look so great.

A source revealed to People that even though it seemed like Scott had fallen back on his hard partying, alcohol-binging ways while he was on vacation, it's a "good sign" that he decided to come home.

“He could have stayed in Europe if he wanted to,” the source said. “He has been partying for weeks, and it has been catching up to him. He is not 20 anymore and has complained that he is not feeling great. Usually, LA is the place he returns to when he is ready to shape up.”

It seemed like Scott's wild Cannes trip was a direct reaction to Kourt's new relationship, and sources previously revealed to Life & Style that even though Kourt and Scott are over for good, he can't stand to see her with another man.

"Scott will do anything to sabotage Kourtney’s relationship, including showing up wherever Kourtney and Younes are hanging out together,” the insider revealed. “He’s also been asking around, trying to get some dirt on Younes so he can bring it back to Kourt and persuade her to dump him."
